Rod is parallel
in all cases.
Pins include
tibial slope.
With the knee flexed at 90 degrees, place the tibial resection
guide with uprod assembly onto the proximal anterior
medial aspect of the tibia and both plateaus. Avoid using
excessive force to seat the guide. Apply most of the force
anterior to posterior while holding the guide as described.
To assist in the medial/lateral positioning of the tibial pin
guide, refer to the last page of the Patient Proposal which
contains a top view of the patient’s tibial surface. It is
recommended to visualize the red line shown in the
Patient Proposal to the patient’s bone and to check
alignment with the raised line on the lateral aspect of the
tibial pin guide (Figure 4).
The planned Varus/Valgus (V/V) alignment can be confirmed
by verifying the alignment of the rod to the patient’s tibial
crest and center of the ankle (Figure 5). The rod is designed
to be parallel to the mechanical axis of the tibia regardless of
the planned tibial slope, when viewed laterally.
Note: The position of the line in the Patient Proposal
is intended to reference the medial one-third of the
tibial tubercle and not the middle of the tibial crest
(Figure 4).
Note: It is recommended to clear extraneous tissue
along the anterior medial aspect of the tibia. Soft
tissue impingement can impact the fit of the guide
and overall alignment or slope. Visualization in
assessing proper fit observed from a sagittal or side
view is helpful.
Note: To position the guide, apply most of the
pressure to the anterior aspect and the remaining
pressure to the proximal aspect of the guide. This
will help assure proper seating of the guide at the
appropriate resection level. The correct position is
found when there is minimal or no toggling/rocking
of the tibial pin guide.
Once the tibia pin guide and uprod assembly is in the
desired position, hold it in place, and secure it to the bone
by drilling two (recommended P/N 9505-02-302) pins, first
through the lateral and then the medial, drill guide pin
holes (Figure 6).
